I don't think a regular incandescent household bulb would get hot enough. If you can find a halogen flood light it would work nicely. I use a PAR38 halogen flood light as a basking light and it works well. It can also be dimmed to get the temperatures just right. You should be able to find one at most hardware stores.
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
